/ˈmɪɡmətʌɪt
/noun Geology
A rock composed of two intermingled but distinguishable components, typically a granitic rock within a metamorphic host rock: a series of dykes intrude the underlying migmatites...
- He regarded metamorphism and deformation as continuously related processes and found it impossible to accept migmatites as metamorphic rocks.
- In such a scenario, the leucogranite sheets might be interpreted to represent the conduits connecting the granite plutons through the migmatites to the granulites.
- Leucosomes and leucogranites that segregated over variable distances but remained within the migmatites contain entrained inclusion-rich biotite from proximal mesosome-melanosome.
